Insurers are in the process of filing proposed premiums for ACA-compliant nongroup plans that will be available inside and outside of Marketplaces in 2017.

Recent reports by insurers about their experiences during the first two years under the ACA suggest that some assumed that enrollees would be healthier than they turned out to be and set their premiums too low, leading in some cases to significant financial losses for ACA-compliant plans and an expectation that premiums could rise faster in 2017. Some insurers took relatively large premium increases for 2016 to better match premium levels with the costs of their enrollees — which would help to offset the need for 2017 premium increases — but it is too soon to know if these efforts were generally successful or whether losses have continued into 2016.
